Knockouts in main breaker box

I just noticed in my main breaker box I have a few of the plastic bushings that fit in the knockouts missing. I am thinking they are there to protect the wires from the metal edges of the breaker box.

Do I need to have the plastic bushing on all of the holes where I have wires running through?

Yes, you need to have connectors on all the wires entering the panel.
